  • python的des和3des加解密

    1.加密:

    pyDes.des(key, [mode], [IV], [pad], [padmode])
    pyDes.triple_des(key, [mode], [IV], [pad], [padmode])
    
    key     -> Bytes containing the encryption key. 8 bytes for DES, 16 or 24 bytes
           for Triple DES
    mode    -> Optional argument for encryption type, can be either
           pyDes.ECB (Electronic Code Book) or pyDes.CBC (Cypher Block Chaining)
    IV      -> Optional Initial Value bytes, must be supplied if using CBC mode.
           Length must be 8 bytes.
    pad     -> Optional argument, set the pad character (PAD_NORMAL) to use during
           all encrypt/decrpt operations done with this instance.
    padmode -> Optional argument, set the padding mode (PAD_NORMAL or PAD_PKCS5)
           to use during all encrypt/decrpt operations done with this instance.

    实例:

    Example
    -------
    from pyDes import *
    
    data = "Please encrypt my data"
    k = des("DESCRYPT", CBC, "", pad=None, padmode=PAD_PKCS5)
    # For Python3, you'll need to use bytes, i.e.:
    #   data = b"Please encrypt my data"
    #   k = des(b"DESCRYPT", CBC, b"", pad=None, padmode=PAD_PKCS5)
    d = k.encrypt(data)
    print "Encrypted: %r" % d
    print "Decrypted: %r" % k.decrypt(d)
    assert k.decrypt(d, padmode=PAD_PKCS5) == data
